Patent GB-833324-A (GB)
Title: Improvements relating to weighing machines
Inventor: COOPER ARTHUR HENRY
IPC: G01G21/00
Filed: 1955-02-11
Abstract: 833,324. Automatic weighing machines. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 7, 1956 [Feb. 11, 1955], No. 4085/55. Class 40 (1). [Also in Group XL (b)] In a system for automatically stopping the delivery of material from a hopper 4 when a given weight has been discharged, hunting of the weighing device about the balance point is prevented by controlling the valve 5 by a signal representing the velocity as well as the displacement of the scale pan 2. As shown, the pan moves an optical wedge between a lamp and photo-cell and the resulting signal is compared with a standard to produce a displacement signal in amplifier 18 and is differentiated at 20 to produce a velocity signal which is adjustably weighted by an amplifier 21. These signals are combined and the composite signal is compared with a voltage representing the position of the valve, the resultant error signal driving the servomotor. A limiter 23 may be included for limiting the signal when it is in a direction to close the valve. A modification is described, without reference to drawings, in which a spring balance is used.

Title: Improvements in or relating to machines for making pneumatic tyre covers or casings
IPC: B29D30/14
Filed: 1921-02-03
Abstract: 179,312. Dunlop Rubber Co., Ltd., and Macbeth, C. Feb. 3, 1921. Tyres, elastic, special apparatus for making.- In a machine for building-up a tyre, cover on a rotary core, means are provided whereby the angularity of the spinning-down discs during their inward travel is controlled bv the contour of the core. For this purpose, a secondary or driving-disc may be associated with each spinning-down disc and, by gearing or otherwise, a variable velocity-ratio may be maintained between the peripheral speed of the spinning-down disc and the surface-speed of the contacting part of the core. The angle at which the spinning- down disc is first presented to the core may be varied, e.g. by varying the distance between the associated discs. To prevent creasing of the fabric, an air-jet or a mechanical wiper may be arranged in advance of the spinning-down disc. In the construction shown in Fig. 1, the spinning-down disc A is carried by a shaft A<x>, the driving-disc B being mounted on a sleeve B<x> and held by spring-pressure between discs B<1>, B<2> so as to impart a friction drive between the shaft A<x> and disc A. The shaft A<x> is supported in a yoke C which is swivel-muonted in a bracket C<2> reciprocated by the usual slide or carriage. Owing to the two-point contact of the discs A, B with the surface of the, core, the latter are caused to swivel in the bracket C<2> in its forward movement. Fig. 8 shows a modification in which the disc A is of larger diameter than the disc B, the discs being geared together to define the greater peripheral speed of the disc A. An air-jet at D' prevents folding-back of the unattached fabric Z<1>. The angle at which the discs are presented to the core may be varied by altering the eccentricity of the shafts A<x>, Bx.

Abstract: 1,044,805. Electric analogue calculating; counters. SIEMENS - SCHUCKERTWERKE A.G. Jan. 31, 1964 [Feb. 28, 1963], No. 4345/64. Headings G4D and G4G. An integrating device comprises a transformer having a ferro-magnetic core and a first and a second winding, and an amplifier having an output connected to the second winding and an input connected in series with the first winding. In the circuit shown in Fig. 2, the input voltage u to be integrated is applied to the winding 3 in series with the input of a high-gain amplifier 6. For this circuit where # is the flux in the core 2, w1 and w2 are the numbers of turns in windings 3 and 4, V is the gain of amplifier 6, and the other quantities are as shown. If V is large the second term is small and the relationship between u and # is nearly integral. If the core 2 has an air gap the current ia is a measure of the time integral of the input voltage and may be evaluated either directly or as a voltage drop across the resistance 5. With this arrangement the integration time may be over one minute; for longer integration times the output across R2 may be fed to a switching amplifier S which reverses the connections of the input signal to the input terminals and passes a pulse to a pulse counter Z each time the current ia reaches a predetermined maximum value, Fig. 3 (not shown).

Title: Improvements in or relating to fuel injection pumps for internal combustion engines
Inventor: MARTYN LAURENCE FREDERIC
IPC: F02M41/12
Filed: 1961-02-06
Abstract: 1,014,191. Reciprocating pumps. SIMMS GROUP RESEARCH & DEVELOPMENT Ltd. March 30, 1962 [Feb. 6, 1961], No. 4410/61. Heading F1A. In a fuel injection pump the effective piston stroke length is controlled by a governor piston 15 in dependence on the rate of operation of the pumping assembly 1, 3. At each injection stroke fuel is forced by enlargement 11 through passages 12, 13, 16, 17 to unseat ball-valve 18 and thence through grooves 20a to emerge at face 20. Fluid pressure forces governor piston 15 to the left against the base of spring 3 to allow fuel, being pumped by piston 1 through passages 6, 7, 8, to be spilled-off when space 26 opens to passage 27. On the return stroke of piston 1 ball-valve 18 closes and fuel returns through a cut-away 21, adjustable by rotation of the governor piston 15, to passage 30. The amount of leakage which takes place determines the starting position of governor piston 15 at the next fuel injection stroke, so that less movement of governor piston 15 is required before spill occurs and fuel delivery is terminated at an earlier stage in the stroke of piston 1. An additional spill passage 27a is opened by end face 20 to give optimum governor action. Axial movement of plug 25 controls the maximum engine load and control rod 24 is withdrawn to increase the fuel supply for starting. The piston 1 is rotated to deliver fuel through other passages 8 (not shown) and helical grooves and a spill passage may be provided to control spill for the respective cylinders. Other inlet passages 5 may be provided.

Title: Process for improving the adhesion of bituminous or other hydrocarbon binders to solid materials
IPC: C08L95/00
Filed: 1955-02-15
Abstract: An aqueous dispersion of a water-insoluble amino compound, in which the dispersing agent is an anionic surface active metal salt or sodium or potassium carbonate or bicarbonate, is used for pretreating a solid material in order to improve the adhesion thereto of a bituminous or other hydrocarbon binder (see Group V). The amino compound may be (a) a higher alkyl or alkenyl amine, e.g. hexadecylamine, heptadecylamine octadecylamine, or octadecenylamine or a polyalkylene polyamine; (b) an amide obtained by condensing ammonia or an amine with a long chain organic acid, e.g. oleic, linoleic, or stearic acid, naphthenic acids, or tall oil acids; (c) an acylamidoamine obtained by condensing a long chain organic acid as in (b) with a polyamine, e.g. ethylene diamine, propylene diamine, diethylene triamine, triethylene triamine, tetraethylene pentamine, hexamethylene diamine, or a polyamine obtained by hydrogenation of the condensation product of acrolein or epichlorhydrin with ammonia; or (d) a tertiary amine containing an alkyl group and two polyoxyethylene groups.  The anionic surface-active agent may be a higher fatty acid soap, an organic sulphate or sulphonate, a resinate or naphthenate, e.g. sodium resinate derived from tall oil or secondary alkyl sulphates derived from cracked paraffin wax.  The amino compound may be present in the dispersion in an amount of 1-30 per cent by weight and the dispersing agent in an amount of 1-10 per cent by weight.ALSO:In order to improve the adhesion between a solid material and a bituminous or other hydrocarbon binder, the solid material is pretreated with an aqueous dispersion of a water-insoluble amino compound, the dispersing agent being an anionic surface-active metal salt or sodium or potassium carbonate or bicarbonate (see Group III).  A suitable proportion of the amino compound is 0,01-1 part per 1000 parts by weight of the solid material.  The dispersion is especially suitable for coating a basic aggregate, e.g. limestone, or a porous aggregate, e.g., quartzite mixed with clay.  Granite feldspar, metals, glass and cement are other solid materials mentioned.  An alkaline filler, e.g., lime, magnesium oxide, or barium hydroxide, may be mixed with the aggregate.  The bituminous binder may be used in an amount of 0,5-10 per cent by weight of the aggregate and may be, for example, straight run bitumen, blown bitumen, natural asphalt, pitch, or wood or coal tar, it may be applied as a cutback or an aqueous dispersion.  The aqueous dispersion of the amino compound may be applied to the aggregate by spraying or other methods.  A wet road surface may be treated with the dispersion before spreading a new layer of binder. Gravel containing a high proportion of fine particles may be pretreated with a part of the total amount of aqueous dispersion, the rest of the aqueous dispersion being added after the binder.

Title: Improvements in or relating to profile turning lathes
IPC: B23Q35/18
Filed: 1950-02-22
Abstract: 682,337. Copying lathes. CHURCHILL-REDMAN, Ltd., and DODGSON, F. Feb. 22, 1950, No. 4508/50. Class 83 (iii). A copying lathe having a chuck carried by a work spindle is provided with hydraulic means for carrying out the following operations: (a) entering a work-piece into the chuck, (b) closing the chuck, (c) moving a tool-slide quickly up to the work, (d) feeding the tool-slide, (e) varying the position of a tool in accordance with a control template, (f) moving the tool clear of the work after the feed has been arrested, (g) quick-return of the tool-slide and release of the work from the chuck. The whole of the hydraulic system for the lathe is housed in a casing g between the bed a and a base f. A rotary pump h driven by an electric motor l draws oil from a sump in the lower part of the casing g and delivers it under pressure to a relief valve h<SP>2</SP> which is set to determine the maximum operating pressure for the system.. From valve h<SP>2</SP> oil is delivered to a distribution valve i controlled from a pedal i<SP>3</SP>, movement to the right or left of which determines whether a tailstock ram j advances and a hydraulicallyoperated chuck c sequentially closes, or vice versa. When the chuck-jaws close on a workpiece pressure rises in the system and a valve m opens against spring pressure to pass oil to the feed-circuit of the machine through a four-way valve n corresponding to valve i. The valve n may be set for rapid traverse or slow feed by a lever p. The hydraulically fed tool carrier d<SP>1</SP> which carries a tracer finger, forming part of known tracing means, moves into the work until the latter contacts the template, whereupon pressure oil is passed to the right-hand end of the main feed cylinder d<SP>3</SP> for effecting the longitudinal movement of carriage d. A cylinder t is simultaneously supplied with pressure oil to operate an arm t<SP>2</SP> and lever t<SP>3</SP> to start up the work spindle. The lever i<SP>2</SP> connected to the pedal i<SP>3</SP> is automatically locked by the plunger of a cylinder u to prevent accidental opening of the chuck by depression of pedal i<SP>3</SP> to the right during working. When the tool-slide reaches the end of the required forward travel a part wa movable therewith engages a part w which causes the control lever p to move over to the quick-return position. At the same time pressure is directed to a tool relief valve x to bring the tool away from the work. Return motion of the slide is limited by a part wb movable therewith which engages a dog w<SP>1</SP> controlling a relief valve. The work spindle is automatically stopped by the built-up pressure caused by the tool-slide reaching the end of its travel acting on the piston in cylinder t. Movement of the pedal i<SP>3</SP> to the right is now possible, which withdraws the tailstock ram and opens the chuck c.
